The Cullens are a fictional family of vampires from the Twilight series, created by author Stephenie Meyer. They are known for their unique lifestyle, which involves abstaining from human blood and instead feeding on animal blood. This choice sets them apart from traditional vampires and allows them to coexist more peacefully with humans. The family is led by Carlisle Cullen, a compassionate vampire who values human life. Each member of the Cullens has a distinct personality and special abilities, such as Edward Cullen's mind-reading and Alice Cullen's precognition. Together, they navigate the challenges of living in a world that fears their kind.
